And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0036] This embodiment provides an ultrasonic imaging device.

[0037] Please refer to Figures 1-4 , this ultrasonic imaging device includes an ultrasonic probe 1000, an ultrasonic host (not shown), and a display device (not shown).

[0038] The ultrasonic probe 1000 is used to emit ultrasonic waves to a target tissue and receive corresponding echo signals. The ultrasonic main unit is connected to the ultrasonic probe 1000, and the ultrasonic main unit is used to process the echo signals to generate ultrasonic images. The display device is connected to the ultrasonic main unit, and the display device is used to display the ultrasonic images.

[0039] When using the ultrasonic imaging device for examination, ultrasonic waves are emitted to the target tissue of the person to be examined through the ultrasonic probe 1000, and corresponding echo signals are received through the ultrasonic probe 1000. Then, the echo signals are processed by the ultrasonic main unit to generate ultrasonic images, and finally the ultrasonic images are displayed on the display device.

[0040] On the other hand, the present embodiment also provides an ultrasonic probe 1000, which can be applied to the above-mentioned ultrasonic imaging device.

[0041] Please refer to Figures 1-4 , the ultrasonic probe 1000 includes a housing assembly 100, a sound head base 200, a sound head assembly 300 and a sealing ring 400.

[0042] Please refer to Figures 1-3 , the housing assembly 100 includes a sound head housing 110 and a connection housing 120. The sound head housing 110 is detachably connected to the connection housing 120, and the sound head housing 110 and the connection housing 120 jointly enclose an installation cavity 130. The sound head base 200 is installed in the installation cavity 130, and the sound head base 200 is fixedly connected to the housing assembly 100 or integrally formed with the housing assembly 100. The sound head assembly 300 is connected to the sound head base 200, and the sound head assembly 300 is located in the internal space of the sound head housing 110. The sealing ring 400 is located on the side where the sound head housing 110 is docked with the connection housing 120. When the sound head housing 110 is docked with the connection housing 120, the sound head housing 110 is used to abut against the sealing ring 400 and press the sealing ring 400 in the direction of the connection housing 120.

[0043] On the one hand, since the sound head housing 110 is detachably connected to the connection housing 120, when maintenance work is required, the sound head housing 110 can be detached from the connection housing 120 to expose the sound head assembly 300, so as to facilitate the maintenance of the sound head housing 110, the connection housing 120 or the sound head assembly 300, thereby improving the maintainability of the ultrasonic probe 1000. On the other hand, since a sealing ring 400 is provided on the side where the sound head housing 110 is docked with the connection housing 120, the sealing ring 400 seals the gap between the sound head housing 110 and the connection housing 120, and by abutting the sound head housing 110 against the sealing ring 400 and pressing the sealing ring 400 in the direction of the connection housing 120, the sealing effect of the sealing ring 400 is further improved by the extrusion force between the sound head housing 110 and the connection housing 120.

[0044] It should be noted that the ultrasonic probe 1000 can be a volumetric ultrasonic probe 1100 for intracavitary examination of the human body, or an ordinary ultrasonic probe for extracorporeal examination of the human body.

[0045] On the other hand, the present embodiment also provides a volumetric ultrasonic probe 1100, which can be applied to the above ultrasonic imaging device.

[0046] Please refer to Figures 1-4 , the volumetric ultrasonic probe 1100 includes a housing assembly 100, a transducer base 200, a transducer assembly 300 and a sealing ring 400. The housing assembly 100 includes a transducer housing 110 and a connecting housing 120. The transducer housing 110 is detachably connected to the connecting housing 120, and the transducer housing 110 and the connecting housing 120 jointly enclose an installation cavity 130. The transducer base 200 is installed in the installation cavity 130, and the transducer base 200 is fixedly connected to the housing assembly 100 or integrally formed with the housing assembly 100. The transducer assembly 300 is connected to the transducer base 200, and the transducer assembly 300 is located in the internal space of the transducer housing 110. The sealing ring 400 is located on the side where the transducer housing 110 is docked with the connecting housing 120. When the transducer housing 110 is docked with the connecting housing 120, the transducer housing 110 is used to abut against the sealing ring 400 and press the sealing ring 400 in the direction of the connecting housing 120.

[0047] On the one hand, since the transducer housing 110 is detachably connected to the connecting housing 120, when maintenance work is required, the transducer housing 110 can be detached from the connecting housing 120 to expose the transducer assembly 300, so as to facilitate the maintenance of the transducer housing 110, the connecting housing 120 or the transducer assembly 300, thereby improving the maintainability of the volumetric ultrasonic probe 1100. On the other hand, since the sealing ring 400 is provided on the side where the transducer housing 110 is docked with the connecting housing 120, the sealing ring 400 seals the gap between the transducer housing 110 and the connecting housing 120, and by abutting the transducer housing 110 against the sealing ring 400 and pressing the sealing ring 400 in the direction of the connecting housing 120, the sealing effect of the sealing ring 400 is further improved by the extrusion force between the transducer housing 110 and the connecting housing 120, thereby effectively preventing the coupling liquid in the installation cavity 130 from leaking from the gap between the transducer housing 110 and the connecting housing 120.

[0048] It can be understood that since the installation cavity 130 of the volumetric ultrasonic probe 1100 usually needs to be filled with coupling liquid to better transmit ultrasonic waves. Therefore, in order to prevent the coupling liquid from leaking from the gap between the transducer housing 110 and the connecting housing 120, the installation position and pressing method of the above sealing ring 400 are particularly important in the volumetric ultrasonic probe 1100.

[0049] Please refer to Figures 1-3 In one embodiment, the acoustic head housing 110 includes a first side 111 and a second side 112. The first side 111 of the acoustic head housing 110 is used to wrap the array element of the acoustic head assembly 300, and the second side 112 of the acoustic head housing 110 is used to dock with the connection housing 120. The second side 112 of the acoustic head housing 110 is provided with a resisting portion 114, and the resisting portion 114 resists the sealing ring 400.

[0050] When the acoustic head housing 110 is installed on the connecting housing 120, the array element of the acoustic head assembly 300 is covered by the first side 111 of the acoustic head housing 110, and the acoustic head housing 110 is connected to the connecting housing 120 through the second side 112, and at this time, the abutment portion 114 located on the second side 112 of the acoustic head housing 110 abuts against the sealing ring 400, so that the sealing ring 400 is pressed toward the connecting housing 120 through the abutment portion 114. Specifically, the acoustic head housing 110 can be detachably connected to the connecting housing 120 by means of threaded connection or snap connection.

[0051] Please refer to Figures 1-3 In one embodiment, a first docking port 113 is provided on the second side 112 of the acoustic head housing 110 . The first docking port 113 is communicated with the inner space of the acoustic head housing 110 . The abutment portion 114 is configured as a sealing groove 115 surrounding the first docking port 113 .

[0052] When the sound head housing 110 is docked with the connecting housing 120, the first docking port 113 can be used to connect the internal space of the sound head housing 110 with the internal space of the connecting housing 120. Since the abutting portion 114 is configured as a sealing groove 115, when the sealing groove 115 abuts against the sealing ring 400, it can not only play a role in pressing the sealing ring 400, but also play a certain positioning role for the sealing ring 400, so that the sealing groove 115 can not only improve the sealing effect of the sealing ring 400, but also make the installation effect of the sealing ring 400 more stable. And the sealing groove 115 surrounds the first docking port 113, so that the sealing groove 115 can provide a 360° clamping force on the sealing ring 400, avoiding the position where the sealing ring 400 is not clamped. In other embodiments, the abutting portion 114 can also be configured as a clamping block.

[0053] Please refer to Figures 1-3 In one embodiment, the sealing groove 115 includes a sealing side wall 1151 and a sealing boss 1152 . The sealing side wall 1151 and the sealing boss 1152 are both arranged around the first docking port 113 , and the sealing boss 1152 protrudes from the inner wall of the sealing side wall 1151 .

[0054] When the transducer head housing 110 is docked with the connection housing 120, a pressing force towards the connection housing is applied to the sealing ring 400 through the sealing boss 1152. On the one hand, the sealing side wall 1151 serves to prevent the sealing ring 400 from being directly exposed to the outside, and on the other hand, it also serves to position the sealing ring 400 along the circumferential side of the transducer head housing 110.

[0055] Please refer to Figures 1-3 , in one embodiment, the connection housing 120 has a third side 121 facing the transducer head housing 110, and the third side 121 of the connection housing 120 has a second docking port 122. When the transducer head housing 110 is connected to the connection housing 120, the second docking port 122 is docked and communicated with the first docking port 113, and the transducer head base 200 is connected to the inner wall of the connection housing 120 and passes through the first docking port 113 and the second docking port 122. An installation groove 140 is provided on the first side 111 of the connection housing 120 and / or the transducer head base 200, and the installation groove 140 is used for installing the sealing ring 400.

[0056] When the transducer head housing 110 is docked with the connection housing 120, the internal space of the transducer head housing 110 is communicated with the internal space of the connection housing 120 through the first docking port 113 and the second docking port 122. Since the transducer head base 200 is connected to the inner wall of the connection housing 120, when assembling the volumetric ultrasound probe 1100, the sealing ring 400 can be first installed in the installation groove 140 on the connection housing 120 and / or the transducer head base 200, and then the transducer head housing 110 is connected to the connection housing 120, and the sealing ring 400 is pressed into the installation groove 140 through the abutting portion 114 of the transducer head housing 110.

[0057] Please refer to Figures 1-3 , in one embodiment, the third side 121 of the connection housing 120 has a first recess 141, and the position of the transducer head base 200 adjacent to the first recess 141 has a second recess 142. The first recess 141 is communicated with the second recess 142 so that the first recess 141 and the second recess 142 jointly form the installation groove 140.

[0058] The installation groove 140 is jointly formed by the first recess 141 and the second recess 142, that is, the installation groove 140 is provided on the third side 121 of the connection housing 120 and the transducer head base 200, so as to jointly position the sealing ring 400 through the first recess 141 of the connection housing 120 and the second recess 142 of the transducer head base 200. Of course, in other embodiments, the installation groove 140 can also be only provided on the third side 121 of the connection housing 120, or the installation groove 140 is only provided on the transducer head base 200.

[0059] Please refer to Figures 1-3, in one embodiment, the sound head base 200 is connected to the inner wall of the connection housing 120, and the sound head housing 110 is threadedly connected to the sound head base 200 and / or the connection housing 120.

[0060] Since the sound head base 200 is connected to the inner wall of the connection housing 120, when at least one of the sound head base 200 and the connection housing 120 is detachably connected to the sound head housing 110, a detachable connection between the sound head housing 110 and the connection housing 120 can be directly or indirectly achieved. The advantage of the threaded connection between the sound head housing 110 and the sound head base 200 and / or the connection housing 120 is that the threaded connection has high reliability and is convenient for disassembly and assembly. In other embodiments, a snap connection can also be used to achieve the detachable connection between the sound head housing 110 and the connection housing 120.

[0061] Please refer to Figures 2-4 , in one embodiment, the inner wall of the sound head housing 110 has an internal thread 116, and the side of the sound head base 200 has an external thread 210. Alternatively, the inner wall of the connection housing 120 has an internal thread 116, and the outer wall of the sound head housing 110 has an external thread 210. Alternatively, the inner wall of the sound head housing 110 has an internal thread 116, and the outer wall of the connection housing 120 has an external thread 210, and the internal thread 116 is threadedly connected to the external thread 210.

[0062] When the sound head housing 110 needs to be installed on the connection housing 120, the installer can dock the sound head housing 110 with the connection housing 120 and make the internal thread 116 on the inner wall of the sound head housing 110 cooperate with the external thread 210 on the sound head base 200, and then rotate the sound head housing 110 so that the sound head housing 110 is gradually screwed in and connected to the sound head base 200. It can be understood that the setting positions of the internal and external threads 210 are not limited. For example, the inner wall of the connection housing 120 can have an internal thread 116, and the outer wall of the sound head housing 110 can have an external thread 210. Alternatively, the inner wall of the sound head housing 110 can have an internal thread 116, and the outer wall of the connection housing 120 can have an external thread 210.

[0063] Please refer to Figures 2-4 , in one embodiment, the inner wall of the sound head housing 110 has an internal thread 116, the sound head housing 110 has a first side 111 and a second side 112. The first side 111 is used to wrap the elements of the sound head assembly 300, and the second side 112 is used to connect to the connection housing 120. A contact portion 114 is provided on the second side 112 of the sound head housing 110, and the contact portion 114 is used to contact the sealing ring 400. The internal thread 116 is located between the first side 111 and the contact portion 114 of the sound head housing 110.

[0064] Since the internal thread 116 is provided between the first side 111 of the acoustic head housing 110 and the abutting portion 114, and the sealing ring 400 is located at the end of the connecting housing 120 facing the acoustic head housing 110. When the acoustic head housing 110 is docked with the connecting housing 120, the abutting portion 114 first contacts the sealing ring 400 and presses the sealing ring 400, thereby preventing the internal thread 116 from contacting and rubbing against the sealing ring 400, which is beneficial to ensuring the sealing effect of the sealing ring 400.

[0065] Please refer to Figures 1-3 , in one embodiment, the volumetric ultrasound probe 1100 further includes a handle housing 150 and a handle base 500. The connecting housing 120 has a fourth side 123 away from the acoustic head housing 110. The handle housing 150 is connected to the fourth side 123 of the connecting housing 120, and the handle base 500 is connected between the connecting housing 120 and the handle housing 150. The acoustic head assembly 300 is rotatably connected to the acoustic head base 200. A driving assembly 600 is provided on the handle base 500, and the driving assembly 600 is connected to the acoustic head assembly 300 for driving the acoustic head assembly 300 to rotate.

[0066] By providing the handle base 500 between the connecting housing 120 and the handle housing 150, the connecting housing 120 and the handle housing 150 can be hermetically isolated through the handle base 500, and an installation position for the driving assembly 600 is provided through the handle base 500, so as to drive the acoustic head assembly 300 to rotate on the acoustic head base 200 through the driving assembly 600.

[0067] It should be noted that when the volumetric ultrasound probe 1100 is applied to perform an intracavitary examination on a subject to be examined, the user can hold the handle housing 150 and insert the acoustic head housing 110 and the connecting housing 120 into the human body, so as to facilitate the examination of the target tissue in the human body through the acoustic head assembly 300 in the acoustic head housing 110, and it is convenient for the user to perform various operations on the volumetric ultrasound probe 1100 through the handle housing 150 located outside the human body.

[0068] Please refer to Figures 1-3 , in one embodiment, the driving assembly 600 includes a driving motor 610, a transmission member 620 and a driving wheel 630. The driving motor 610 is connected to the side of the handle base 500 facing the handle housing 150.
